PANDAS, or Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections, is a rare condition that can cause dramatic behavioral changes in children. It is believed to be triggered by an autoimmune response to a streptococcal (strep) infection, such as strep throat or scarlet fever, which results in the production of antibodies that attack the brain. This can lead to a range of symptoms, including obsessive-compulsive disorder (OCD), tic disorders, mood changes, anxiety, and more. While PANDAS is typically associated with strep infections, there may be other triggers, and the diagnosis and underlying cause are still a subject of research.

PANDAS is an abbreviation for Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections
PANDAS is a rare condition that typically first appears in childhood, from age 3 to puberty, although it can occur in adolescents and adults. The symptoms of PANDAS come on suddenly and can last a few days to weeks. They may go away and then return later. The symptoms of PANDAS include obsessive-compulsive disorder (OCD) and/or tic disorders, which can be motor or vocal tics, obsessions, and/or compulsions. In addition to these symptoms, children with PANDAS may become moody, irritable, or anxious, experience anxiety attacks, or show signs of separation anxiety. They may also have symptoms similar to those of attention-deficit/hyperactivity disorder (ADHD), such as hyperactivity, inattention, or fidgeting.
The underlying cause of PANDAS is thought to be an autoimmune attack of healthy brain tissue after a strep infection. During a Group A Streptococcal (GAS) bacterial infection, the immune system mounts an adaptive immune response to destroy the invading bacteria by producing antibodies and strep-specific T-cells. In some cases, these antibodies inadvertently target the child's own healthy tissue in the brain, resulting in neuropsychiatric symptoms. The specific mechanism or cause is still being studied, but researchers believe it may be similar to that of rheumatic fever, an autoimmune disorder triggered by strep throat infections.
The diagnosis of PANDAS is based on clinical criteria, as there are no lab tests available for diagnosis. Health care providers use the following criteria for diagnosis: abrupt "overnight" OCD or dramatic, disabling tics; a relapsing-remitting, episodic symptom course; young age at onset (average of 6-7 years); presence of neurologic abnormalities; and a temporal association between symptom onset and Group A strep (GAS) infection. Treatment for PANDAS typically involves medication and therapy, including antibiotics to treat the underlying strep infection.

PANDAS is a type of pediatric acute-onset neuropsychiatric syndrome (PANS)
PANDAS, or Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections, is a type of pediatric acute-onset neuropsychiatric syndrome (PANS). It is a neurological and psychiatric condition in which symptoms are brought on or worsened by a streptococcal (strep) infection, such as strep throat or scarlet fever.
PANDAS is characterised by the abrupt onset of obsessions, compulsions, or tics, which can be verbal—such as grunting—or the jerking of limbs or the head. These symptoms are usually dramatic, happening "overnight and out of the blue", and can include both motor and vocal tics, obsessions, and compulsions. In addition to these symptoms, children may become moody or irritable, experience anxiety attacks, or show signs of separation anxiety, such as a fear of being away from parents or other caregivers.
PANDAS is typically first diagnosed in childhood, from ages 3 to 12, although it can affect older children and adolescents as well. Reactions to strep infections are rare after age 12, but researchers recognise that PANDAS could occur, although rarely, among adolescents. It is unlikely that someone would experience these post-strep neuropsychiatric symptoms for the first time as an adult, but this has not been fully studied.
The underlying cause of PANDAS is thought to be attributed to an autoimmune attack of healthy brain tissue after a strep infection. Specifically, it is believed that antibodies produced during the adaptive immune response inadvertently target the child's own healthy tissue in the brain. This results in neuropsychiatric symptoms such as OCD, tics, and other behavioural changes.
PANDAS is diagnosed based on clinical features, as there are no lab tests that can diagnose the condition. To meet the criteria for PANDAS, documentation of a preceding strep infection is required, although cases are often diagnosed based on a history of exposure to a known GAS infection. Blood tests may be done if symptoms have been present for more than a week to document a preceding strep infection.

The symptoms of PANDAS include OCD, tics, mood changes, anxiety, and more
PANDAS, or Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections, is a condition in which children experience a sudden onset of OCD, tics, or both following a streptococcal (strep) infection. The symptoms of PANDAS are typically dramatic and can include a range of behavioural and emotional changes.
OCD symptoms in children with PANDAS may manifest as obsessive thoughts, compulsive behaviours, and repetitive actions or habits to avoid anxiety and panic. They may also exhibit tics, which can be either vocal, such as grunting, or motor tics, such as jerking of the limbs or head. These tics can interfere with the child's ability to function.
In addition to OCD and tics, children with PANDAS may experience a range of other symptoms, including mood changes and irritability. They may become moody, anxious, or aggressive and struggle with controlling their emotions or behaviours. They may also experience anxiety attacks and have difficulty with separation anxiety, becoming "clingy" and fearful of being away from their parents or caregivers.
Other symptoms of PANDAS can include symptoms similar to those of attention-deficit/hyperactivity disorder (ADHD), such as hyperactivity, inattention, or fidgeting. Sensory problems may also be present, such as sensitivity to light or hallucinations. In some cases, children with PANDAS may experience depression, sleep issues, or extreme rage.
The symptoms of PANDAS typically appear suddenly and can last from a few days to weeks, with the potential for the symptoms to return or flare up later. The onset of symptoms usually occurs between the ages of 3 and puberty, although it is possible for older adolescents and adults to experience these symptoms, albeit rarely.

PANDAS is typically diagnosed based on clinical features and patient history
PANDAS, or pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections, is a rare condition that can develop after a streptococcal infection, such as strep throat or scarlet fever. The symptoms of PANDAS are usually dramatic and can include obsessive-compulsive disorder (OCD), tics, mood changes, anxiety, and severe separation anxiety.
The diagnosis of PANDAS is typically made based on clinical features and patient history. There are no specific laboratory tests or biomarkers that can confirm the diagnosis. Instead, healthcare providers rely on the patient's symptoms, history of streptococcal infection, and the presence of other criteria to make a diagnosis.
One of the key features of PANDAS is the abrupt onset of symptoms, often described as "overnight" or "out of the blue". This sudden appearance of OCD, tics, or both is a characteristic feature that distinguishes PANDAS from other disorders. The symptoms can be severe enough to interfere with the child's ability to function and may require medical intervention.
To diagnose PANDAS, healthcare providers will assess the patient's symptoms, including the presence of OCD, tics, anxiety, and mood changes. They will also consider the patient's history, including any recent streptococcal infections, such as strep throat or scarlet fever. It is important to note that the streptococcal infection may not always be symptomatic, and a positive throat culture or blood tests showing elevated antibodies against streptococcal bacteria may be necessary for confirmation.
Additionally, PANDAS is often associated with a relapsing-remitting course, with symptoms worsening and then improving over time. This episodic nature of the symptoms is another criterion used in the diagnosis of PANDAS. The presence of neurologic abnormalities, such as abnormal neurological exam findings, can also support a diagnosis of PANDAS.

Treatment for PANDAS involves medication, therapy, and antibiotics to treat the underlying strep infection
PANDAS, or Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections, is a rare condition that can cause a range of psychological and neurological problems in children. It is typically first diagnosed in children from the ages of 3 to 12, with symptoms including obsessive-compulsive disorder (OCD), tics, mood changes, anxiety, and aggressive behaviour. These symptoms can appear suddenly and dramatically, often occurring "overnight and out of the blue".
In addition to antibiotics, cognitive behavioural therapy (CBT) can be used to help children manage the mental and emotional difficulties associated with PANDAS. CBT can provide children with coping skills to deal with their symptoms and decrease their frequency. Habit reversal training is another form of therapy that can be effective in treating tics associated with PANDAS.
In more severe cases, or when other treatments have not been successful, more extreme procedures such as IVIG or plasmapheresis may be considered to reset the immune system. IVIG involves an infusion of antibodies from other people, given through a vein. Plasmapheresis involves removing the child's blood, filtering it through a machine to remove the antibodies attacking their brain, and then returning it to their body. These procedures can be effective in treating PANDAS, but they may take time to show results.
